I do not understand the "h".
Problems with a NEWS suffix sign sounds like a library problem. On a GNU
library 11.3e is interpreted as a positive 11.3 and "e" is still in the
uninterpreded input string.
A proper lexical analyser should sense existance of an e|E followed by a
signed number. The "D" of FORTRAN infamy is not recognized. In any case
proj_dms2rad and preceeding versions have not put a restriction on ddd.dddd.

Don't use %2d as that will cause space for numbers under 10. "%d" will work
OK with proj_dms2rad.

Basic, old time, standard ASCII does *not* have a degree mark and that is why
I have not used it. The degree mark is an addition to some alphabets.
I would use it but I am not a student of all the alphabets available nor do I
want to be and until a standard alphabet is mandated by the US Congress, The
United Nations, or a local star cluster federation, I must stick to old
standards although I would like to use a °.
If this august group of potential users can make an IRON-CLAD guarantee that
latin-1, UTF-8, or whatever set is univerally available to a *all* potential
users and usable in C format operations, I would add the degree mark to the
Thanks for the comments.
